SPECIFICATION forming part of Letters Patent No. 670,402, dated March19, 1901. Application filed April 13, 1900. serial No. 12.757. (Nomodel.)

To all whomz't may concern:

Be it knownthat we, ERNST EMIL voN HEDE- MANN and ROSENOERN voNHEDEMANN, subjects of the King of Denmark, residing at 23 Mariendalsvej,Copenhagen, Denmark, have invented new or Improved Molds for ArtificialStone, of which the following is a specification.

This invention is an improvement in molds for artificial-stone slabs;and its object is to provide a machine by which slabs of various sizesand forms can be manufactured either at the factory or, if desired, atthe location of the building in which the slabs are to be em ployed; andthe invention consists in the novel construction of the apparatus, ashere inafter described with reference to the drawings and summarized inthe claims following such description. v

1n the drawings, Figure 1 is a top plan view of the apparatus, partly insection, showing the parts so adjusted that four independent slabs maybe simultaneously formed. Fig. 2 is a section through the apparatus online 00 00, Fig. 1. Fig. 3 is a top plan view of the apparatus, partlyin section, showingit adjusted to cast one T-shaped and one plain slab.Fig. 4 shows the apparatus adjusted to cast a cruciform slab. Fig. 5 isa similar View of the apparatus to cast one long and two short plainslabs. Figs. 6 and 7 are details showing how the side pieces of the moldmay be hinged.

The apparatus is mounted upon a suitable base 1, which is used to finishone edge and which also forms the bottom of the mold. Upon this base aremounted in cruciform arrangement four molds A B C D, molds A O and B Dbeing arranged oppositely.- The adjoining side walls of molds A and Dand of molds B and C may be'made integral, if desired, and of sheetmetal bent at right angles of proper length and height, corresponding tothe maximum slab to be produced in the mold. The adjoining side walls 7and 9 of molds A and B are preferably made integral and of metal, andthe adjoining side Walls 12 and 13 of molds C and D may also be madeintegral. These side Walls 7 and 9 are movable outwardly by means of ascrew 15, and

so are the walls 12 and'13. In this manner the thickness of the slabs tobe cast is regulated.

If desired, the tops of the walls may be formed by covers 14:, asindicated in Fig. 1, which may be hinged to the fixed sides, ifpreferred. The ends of the molds may be formed by blocks 20, asindicated in Fig. 1. These may be located anywhere along the length ofthe mold, according to the length of the slab to be cast, and if it isdesired to make the slabs hollow cores E may be inserted longitudinallyof the molds, as indicated in Fig. 2.

The extreme outer ends of the mold may a T-slab, a single filler-block20 is placed in one of the molds, as B, Fig. 3, and then the slab castin molds A O D will be integral of T shape, and at the same time a smallslab may be cast in mold'B, if desired. If it is desired to cast anextra long slab and one short slab, two fillerblocks may be placed inthe opposite molds B D, as in Fig. 5, so that the slab cast in mold A Gwill be integral, while short slabs may be cast in molds C D at the sametime, if desired.

If it is desired to cast independent slabs, a central filler-block 6 maybe placed, as in Fig. 1, so that a separate slab can be formed in eachmold.

To remove the mold after the slabs are formed and sufliciently set, theymay be removed from the mold either by opening the ends of the mold orloosening up the removable sides thereof, or, if desired, the stationarysides of the respective molds may be hinged at the bottom, as indicatedin Figs. 3 to 7, so that such sides maybe lowered when it is desired toremove the cast slabs. Of course suitable cores may be used to make theslabs hollow, if it is considered desirable.

From the foregoing description the manner of using the mold and itscapability of producing blocks of various sizes and shapes therein willbe readily comprehended by one skilled in the art and furtherdescription of the operation is unnecessary.

What is claimed as new is 1. In an apparatus for forming artificialstoneslabs, &c., the combination of a pair of molds set at right angles, theinner or opposed walls of adjoining molds being connected and adjustabletogether directly to or from the outer walls thereof, substantially asand for the purpose described.

2. In an apparatus for forming artificial stone, the combination of aplurality of molds set at right angles, the inner or opposed walls ofadjoining molds being adjustable bodily and together to or from theouter walls of such molds; with adjustable pieces or blocks in themolds, substantially as and for the purpose described.

3. The combination of a plurality of molds set at right angles, theinner adjoining walls thereof being connected but adjustable to or fromthe outer walls of the molds, said outer walls being hinged to the base,for the purpose and substantially as described.

4. In an apparatus for forming artificial stone, the combination of aplurality of molds set at right angles, the inner adjoining wallsthereof being connected but adjustable to or from the outer walls of themolds, said outer walls being fixed to the base, with the adjustablepieces for closing the ends of the molds, and hinged covers for saidmolds, for the purpose, and substantially as described.

5. The combination of molds in cruciform arrangement communicating attheir inner walls thereof, and adjustable blocks in the molds,substantially as described.

7. The combination of a plurality of molds, the adjoining walls ofopposite pairs of adjoining molds being adjustable toward or from thefixed or outer walls of such molds, and mechanism for adjusting saidwalls, and the adjustable blocks within the molds, substantially as andfor the purpose described.

8. In an apparatus for molding artificialstone slabs, the combination offour molds arranged in cruciform style, the adjoining walls of oppositepairs of adjoining molds being rigidly connected and adjustable towardor from the center of the apparatus; with mechanism for adjusting saidwalls, the hinged ends attached to the molds, and the adjusta le blockswithin the molds for regulating the shape and size of the slabs therein,substantially as and for the purpose described.

9. In apparatus for molding artificial-stone slabs, 85c. the combinationof molds arranged in cruciform style, the adjoining walls of oppositepairs of adjoining molds being adjustable toward or from the other wallsthereof, and mechanism for adjusting said walls, adjustable blockswithin the molds for regulating the shape and size of the slabs therein,the walls of the molds opposite the adjustable walls being hinged, andeach mold being provided with covers, substantially as and for thepurpose described.

10. In apparatus for moldingartificial stone, the combination of fourmolds arranged in cruciform style, the two adjoining walls of adjoiningmolds being rigidly connected so as to be adjustable toward or from thecenter of the apparatus,and mechanism for adjusting said walls, thewalls of the molds opposite the adjustable walls being hinged; withhinged ends attached to the molds, the adjustable blocks within themolds for regulating the shape and size of the slabs therein, and acover for each mold, substantially as and for the purpose set forth.

In witness whereof we have hereunto set our hands in presence of twowitnesses.
